Plastic Jug Filter
This instructable shows how to turn an HDPE plastic jug into a filter. This can be used to filter particulates from a chemical experiment for instance.
Form the Funnel
The top of the jug becomes the funnel:
- Use something to support a permanent marker.
- Keep the marker stationary and rotate the bottle to mark the level.
- Cut off the lid and handle.
- Trace and cut to make a funnel.
- Heat where the handle used to be and flatten.
- Heat and apply extra patch of plastic for the handle hole.
Form Stop Tabs
To keep the funnel from falling or rotating into the 'bucket' part of the jug, make four tabs:
- Heat and squish the handle.
- Cut square pieces from the squished slab of plastic.
- Solder the tabs onto the funnel.
Create Support Net
Create a support net for the funnel's filter:
- Cut thin strips of HDPE and tape them down in equal spacing.
- Overlay additional strips.
- Heat using a heat gun or embossing tool.
- Squish with a wooden block.
Solder and Use
In the last step, solder the mesh to the funnel and use:
- Tack the mesh onto the funnel.
- Cut excess length.
- Solder all pieces.
- Put funnel over bucket.
- Insert a paper filter.
- Use.
